The week in wildlife – in pictures

A brown bear gazes away from its own reflection in a lake in Kainuu, Finland. With the stillness of the water and the woods around it, an almost perfect, mirror dreamscape forms.

The brown hairstreak has a reputation for being one of the most difficult butterflies to photograph. It is genuinely uncommon, occurring at lower densities than the other hairstreaks, and has a highly localised distribution in southern Britain. It also tends to keep out of camera's reach in the tops of trees and Blackthorn hedges, though it is sometimes tempted lower to feed on flowers. It is so elusive that Butterfly Conservation cannot give a population trend. Surprisingly, most records are of eggs found during winter.
